An Artificial Solid Electrolyte Interphase Layer for Stable Lithium Metal Anodes

Abstract
A Li3PO4 solid electrolyte interphase (SEI) layer is demonstrated to be stable in the organic electrolyte, even during the Li deposition/dissolution process. Thus, the Li‐conducting Li3PO4 SEI layer with a high Young's modulus can effectively reduce side reactions between Li metal and the electrolyte and can restrain Li dendrite growth in lithium‐metal batteries during cycling.
